WebExplanation: Chemical bonds certainly "contain" potential energy, and the atoms want to move to a lower potential energy (become more stable). When methane, CH4, forms, the valence electrons end up in more stable (lower energy) C-H bonds. These bonds are fairly strong, so methane is relatively inert. However, if you add energy to the methane in ... html code red color
